cfg80211/mac80211: refactor cfg80211_chandef_dfs_required()
Some interface types don't require DFS (such as STATION, P2P_CLIENT etc). In order to centralize these decisions, make cfg80211_chandef_dfs_required() take the iftype into consideration. Signed-off-by: Luciano Coelho <luciano.coelho@intel.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
